I am using VS2008 Version 3.5 SP1.

Initially I build my code with "Any CPU" setting in Configuration Manager.
It worked fine on 32-bit but did not work on 64-bit platform.
In order to run the code on 64-bit platform, I build and compiled the code with "x86" setting in Configuration manager.
But still the dll does not work.

Whatsettings need to be done to run a 32-bit compiled code on 64-bit platform?

Thanks

This is a 32-bit COM component. You cannot use the "Any CPU" setting, you must select x86.

"Does not work" doesn't help us help you. Setting the platform target on a DLL has no effect. The setting for the EXE is what counts.

The application hasone EXE and uses 2 different dlls, based on options selected by the user.
One of the dll works fine with the same EXE but other does not. Although both have the same settings ie "Any CPU".
Except the dll in question uses Microsoft Dynamics AX Business COM Connector.
I get an error "Vendor Assembly could not be loaded : Path specified was : C:\Program Files (x86)\...\ abc.dll"

But the dll exists in the specified location.

This is a 32-bit COM component. You cannot use the "Any CPU" setting, you must select x86.

Thanks for your quick reply.

Is the 64-bit COM component available for AX 4.0 SP2? If yes, how can it be obtained?

Thanks again

Don't ask here, ask in a Dynamics forum.
